14th Army was the name of the army in Burma.
The army is made up of Corps.
Corps are made up of Divisions.
Divisions are made up of Regiments and Battalions.
Your father-i-l was in 17th Indian Division.
In my earlier post I listed the British units in the 17th.
If , however, he was at the Commissioners bungalow then he was in the Royal West Kent Regt, but the black cat was not their emblem.
His service history will reveal all.
It is unlikely he was a Chindit unless he specifically mentioned it.
The 14th Army were called the 'Forgotten Army' as they felt they came second to the war in Europe, which is probably partly true as the folks at home were more involved in the European war, it being 22 miles away!
